There are several fabrication shops with total are + 12,500 SQM, complete with equipment to fabricate of pipe spools, assembly of pressure vessels, skid mounted process equipment, electrical and instrumentation.
The area of each Shop as follows:
1. Fabrication Shop 1 : 90 x 16 SQM 2. Fabrication Shop 2 : 90 x 30 SQM 3. Fabrication Shop 3 : 54 x 26 SQM 4. Fabrication Shop 5 : 140 x 30 SQM plus 84 x 17 SQM 5. Fabrication Shop 6 : 55 x 24 SQM 6. Portable Shops.
Equipment in this area as follows:
Miscellaneous Shops
One of miscellaneous shops which area of 2400 SQM for cutting and profil
Warehouse Area
There are 2 (two) covered warehouse which has on overall surface in the total area 2,012 SQM. 1 (one) warehouse at inside of gate-2 and the other one is at yard-2. Both warehouses are available as customs bonded warehouse:
1. Warehouse-1 at inside of yard-1 = 20 x 41 SQM (1 bay)
2. Warehouse-2 at inside of yard-2 = 52 x 54 SQM (3 bays)
Material Storage Area
The Customs bonded steel material open storage is approx. 176,559 SQM and has able space for storage of both Client (s) and Contractors materials. The open storage area is split into 2 locations:
Open storage inside yard-1
Open storage inside yard-2
Material Handling
All workshops are equipped with various capacity of overhead traveling cranes.PTG has own traveling cranes to support the construction activities at open area, i.e.:
It is possible to rent from local crane Rental Company.
Working Tables
There are 2 (two) units working table with the following dimension:
1. Working table-1 at inside yard-1 = 20x48m 2. Working table-2 at inside yard-2 = 2@15x30m
In which generally to be used for assembly of deck section and pre-fabrication of beams and branches.
Jetty
There are 2 (two) jetties which is used for load-out of structures and most of the offloading and loading of material. The jetty-1 has a bulkhead 106m (length) x 15m (width) and minimum water depth of (-) 7.5m from chart datum. The jetty-2 has a bulkhead 80m (length) x 15m (width) and minimum water depth of (-) 7m from chart datum.
The jetties were designed for distribution load for 500T/m for the 1st of 4m from jetty tip, 400T/m for the 2nd of 4m, 350T/m for the 3rd of 5m and 250T/m along the skid-way.
The minimum water depth at the load-out jetty is (-) 7 up to (-) 7.5m from chart datum and is at least this depth through natural channels leading to the open sea. There is no problem (obstructions, overhead clearance, and bends, channel widths or water depths) in bringing with the structures from the fabrication yard.
Load Out System
The skid-ways were designed for skidding load-out method with skid-way spacing 12.19m/20m at jetty-1 and 15.2m at jetty-2. The bulkhead were build at jetty tip to allow for loading/unloading activity with the capacity for bearing load up to 25 Ton/m2.
The skid-ways are 1.2m (width) x 1.5m (depth) embedded, spaced at 12.19m & 20.00m (skid-way jetty-1) and 15.35m (skid-way jetty-2) center to center. The length of skid-way jetty-1 is 300m and 153m for jetty-2 and both jetty facing to open sea. Along the skid-ways there are electrical outlets for 380 V rectifier-welding machines and compressed air outlets.
The structure/modules can be fabricated in the skid-way up to 100m length and for weighing the structure up to 15.000Te.
Beside skid-way system, the multi-wheel method and the lifting method also possible to use for load-out system at GUNANUSA Fabrication Yard.
